Cabinet Boxes: Plywood or Pressboard – What You Need to Know

When planning a kitchen or bathroom remodel, it's easy to focus on cabinet doors, countertops, and finishes. But what’s inside the cabinets is just as important. This hidden structure plays a big role in your cabinets’ durability, longevity, and overall performance.

Two of the most common materials used for cabinet boxes are plywood and pressboard (also known as particleboard). Each has its pros and cons, and understanding the difference will help you make the best decision for your home and your budget.

Let’s talk more about each option.

What is a Cabinet Box?

The cabinet box is the structure that holds everything together. It's the frame that supports drawers, doors, and shelves. While it might not be top-of-mind, a well-built cabinet box ensures your cabinets stay level, open and close properly, and withstand years of daily use.

Plywood Cabinet Boxes

Plywood is made by gluing together thin layers of wood veneer, with the grain of each layer running perpendicular to the one before it. This cross-grain construction gives plywood strength and stability.

Pros of Plywood:

• Stronger and more durable: Plywood resists sagging, warping, and cracking better than pressboard, especially under heavy loads.

• Better moisture resistance: In a humid environment like a kitchen or bathroom, plywood holds up better over time.

• Longer lifespan: Cabinets with plywood boxes typically last longer and are better suited for high-end renovations.

Cons of Plywood:

• Higher cost: Plywood is more expensive than pressboard, which impacts the overall budget.

• Inconsistent appearance: Since plywood is made from real wood layers, the surface can have natural variations, though these are usually covered with a veneer or laminate.

Pressboard Cabinet Boxes

Pressboard is made by combining wood chips, sawdust, and resin, which are then compressed into sheets. It’s commonly used in stock and budget-friendly cabinets.

Pros of Pressboard:

• Cost-effective: Pressboard cabinets are significantly cheaper than those made with plywood.

• Smooth surface: Great for laminates and veneers, pressboard offers a uniform look without knots or imperfections.

• Lightweight: Easier to transport and install, especially in tight spaces.

Cons of Pressboard:

• Less durable: Pressboard is more likely to sag or break under pressure, especially if not properly supported.

• Poor moisture resistance: Exposure to water can cause swelling and disintegration.

• Shorter lifespan: Over time, pressboard can break down, especially at joints and connection points. However, with proper care, they can have a lifespan of around 15 years.

Which One Should You Choose?

• Choose Plywood if you’re doing a major renovation, want a long-term investment, or are working in a high-moisture environment like a bathroom or coastal kitchen.

• Choose Pressboard if you’re on a tighter budget, remodeling a rental property, or need a quick, affordable upgrade.
